My husband and I both have 6 drawer plastic dressers in a closet, to hold cycling clothes (well, mine also has running/yoga stuff in there, too). We had to buy a clothing rack for drying, because we have so many cycling things that need to be air dried. Every vacation we take has some sort of cycling component, even if it's just tooling around on our hybrids or renting a cruiser. All of our social plans are made with regard for our riding schedule. We still go out with non cycling friends, but "at our convenience."
My husband is commuting a lot more this summer, because of a parking situation at work, where he has to park and take a shuttle because of construction. He cannot park by the building for 3-4 weeks at a time, on a rotating basis. This is going to go on for 3 years. I don't think he will commute in the winter/cold weather, but he might take the hybrid in the car and ride it from the shuttle lot, which is only 2 miles away. I do errands on the bike and am much more conscious of driving, etc.
We don't ride as much as some on this list, but I think most other people would call us obsessed.
